Abstract

Influence of temperature (24°, 28°, 31° or 34°C) was studied on the feeding rate of predatory
cymatiid. Cymatium (Manop/ex) pileare fed with edible oyster.The rate of feeding increased from 2 to
5.3 oysters/gastropod/month as temperature increased from 24° to 31°C. Increase in temperature
decreased the days of feeding interval from 6.3 days at 24°C to 3.7 days at 34°C. All test animals
courted mortality at 34°C on 17th day suggesting it as the upper tolerable limit of temperature.
